As a follow up to Galactic Gains, not even the universe can withstand this enormous mass of lady as she grows larger and larger, in large part by the help of a milky friend!
Another follow up with a close-up of these two coming soon!

Aelynn: The Breast Idol [4]
Potentially the final piece for Aelynn's Breast Adventure ever! For now we close the book on her journey, but while we aren't looking, she's still growing.
Pound by pound, wave after wave of euphoric expansion.
Hope you liked it!

Helpless but to ride out the bliss, the intensity of Aelynn's newfound artifact is unrelenting, causing her body- but primarily her breasts to grow rapidly!
Follow along for the finale!

The second part of Aelynn's breast expansion experience! Courtesy of a wonderful Blobble (blob bauble) that I'll in some way in the future be incorporating into Halcyon Canon.
For now, enjoy it alongside her, reveling in the hundreds of piling pounds

The Debut of Gain Corps!
As mentioned to my Watchers over on DA, this will be my largest and longest running comic. Weight gain, blob, furry, humanoid, bimbofication, corruption, feeding, you name it, look forward to it.
For now, meet Zoey and Millie, one OC and the other from Hazbin Hotel.

The Price of Victory [7]
After finally escaping from the confines of the arena, Po's relief is fatefully short-lived as the Giantess bursts out behind him, summarily toppling her weight downward!
Thankfully no Panda's were harmed in the making of this comic, fat is soft!
